Hi,

Be aware that also your .subscriptions file and .customflags are not nfs safe (yet) in dovecot-0.99.10.

I know Timo is working on that though :)

Kind regards,

Maikel Verheijen.

Ps: I have a "crude" patch to make .subscriptions and .customflags nfs aware (I can not guarentee it is nfs safe ;-). My own setup runs on nfs with the indexes in memory.

I'm migrating our mailserver from cyrus 2.0 to Postfix and Dovecot.

We're using maildirs delivered to /var/maildir, which is mounted via NFS from a Netapp. My understanding was that maildir was completely happy in an NFS environment but I've seen a couple messages here recently which mention the dovecot index files not being NFS safe.

Are their any caveats or gotcha's that I need to be aware of?

You'll probably want to keep them in memory or on local disk. See <http://dovecot.procontrol.fi/doc/nfs.txt> for more information - default_mail_env needs either ":INDEX=/local/path/to/indexes/%u" or ":INDEX=MEMORY", all machines accessing the mailstore should have sync'd clocks, and all imap servers need separate hostnames.
